David Milch, the creator of “Deadwood,” revealed his Alzheimer’s diagnosis in an interview published Tuesday.

“As best I understand it, which is minimally, I have a deterioration in the organization of my brain,” Milch told Vulture. “And it’s progressive. And in some ways discouraging. In more than some ways — in every way I can think of.”

Beginning five years ago, people around him noticed instances of “imperfect recall and tardy recall and short temper,” Milch said. “I became more and more of an acquired taste.”

He also struggled with his writing process, which was characterized by “a generalized incertitude and a growing incapacity.” About a year ago, Milch finally underwent a brain scan and received the diagnosis.
